Description
Technical field:
The utility model mining flame-proof latch connector relates to the interface unit field that power supply switches on and off on the battery locomotive under the coal mine.
Background technology:
Though the mining flame-proof latch connector kind that use the China's coal-mine down-hole is more, but ubiquity the loose contact of inner conductive body, causes interior fusible core of connector or binding post seriously to burn out, and produces to the colliery and brings considerable influence, the repair and replacement cost is very big, and brings safety of coal mines hidden danger easily; In addition, when old-fashioned pinned coupler is pegged graft, promote to insert by manpower entirely, relatively effort for overcoming above-mentioned shortcoming, guarantees that pinned coupler safe ready ground uses, and should design novel mining flame-proof latch connector.
Summary of the invention:
The purpose of this utility model provides a kind of mining flame-proof latch connector, and the conduction assembly is housed in the pinned coupler housing, fusible core, binding post; Be connected respectively to storage battery and load by clamp nut and connection bolt.
A kind of mining flame-proof latch connector, the shell of pinned coupler (42) is by protecgulum (30), plug (1), socket (2), socket (3) and bonnet (4) are formed, part in the shell is by binding post (21), wire harness (18) is flexible coupling, main spring (19), moving contact (17), spring to break (15), fusible core (14), binding post (12), connection bolt (25), Binding post/stud (26) and insulated support are formed, it is characterized in that protecgulum (30) is connected with plug (1), plug (1) is inserted in the socket (2), socket (2) is connected with socket (3), and bonnet (4) is connected with socket (3); Positive stop (22) and boss (34) are arranged on plug (1) outer wall, block (10) is arranged in the inwall; The support of bearing (8) and dust cap support (44) are arranged on socket (2) outer wall; Mounting bracket (45) is arranged on socket (3); Binding post (21) and moving contact (17) are connected with the wire harness that is flexible coupling (18) by clamp nut (36) and clamp nut (38) respectively, and main spring (19) is positioned between binding post insulating case (20) and the insulating case (16); Be crimped with pretension main spring lid (41) between socket (2) and the socket (3); Fusible core (14) is connected with binding post (12) with moving contact (17) respectively; The outer fusible core insulating support (9) that is set with of fusible core (14); Binding post (12) two ends are respectively installed with plug insulating base (13) and anti-rotation insulating case (11), and the block (10) on plug (1) inwall is inserted in the spacing anti-rotation groove (37) of anti-rotation insulating case (11).
The project organization of mining flame-proof latch connector of the present invention is that the plug of pinned coupler is inserted in socket (2) inwall, both make matched in clearance, make pinned coupler housing internal pressure excessive thereby be unlikely, be unlikely that also the interior electric charge of housing is leaked, so but flame proof; Design has pretension main spring lid in pinned coupler, and main spring is carried out pretension; Design has a block in the plug inwall, matches with spacing anti-rotation groove on the anti-rotation insulating case, increases the contact resistance with fusible core to prevent binding post in the anti-rotation insulating case from rotating; Design has the support of bearing on socket (2) outer wall, the support of bearing matches with positive stop on the plug outer wall, the specification requirement principle of above-described mining flame-proof latch connector design all is that the contact resistance between the conductive parts descends in the housing in order to make, and do not cause fusible core, binding post etc. to burn out, guarantee that this pinned coupler uses safely under the colliery, and be convenient to installation and removal.
Below the structure of mining flame-proof latch connector of the present invention is described as follows:
The external shell of this mining flame-proof latch connector is made up of protecgulum, plug, socket (2), socket (3) and bonnet, protecgulum is inserted in the plug ends inwall, protecgulum is connected with plug by attachment screw, the left end collar wall of plug is inserted in socket (2) the inner ring wall, socket (2) left end is connected with socket (3) right-hand member by attachment screw, and bonnet is connected with socket (3) by attachment screw.
Be connected with two supports of bearing on socket (2) right-hand member collar wall, the support of bearing and socket (2) are cast as integral piece, by short pin rolling bearing are installed in the clip slot of each support of bearing left end.
On the collar wall of plug middle part, be connected with the boss of two evaginations, a helical planes is from bottom to top arranged on the right flank of every boss, on each next door, helical planes inboard an antiskid groove is arranged respectively, as shown in Figure 4, when the plug on the pinned coupler by arrow C when being rotated counterclockwise, then the rolling bearing in the support of bearing of socket (2) upwards slides along the helical planes on the boss of plug, the straight rolling bearing that ends drops in the antiskid groove of boss, and at this moment plug just is connected with socket (2) and has put in place.
On the boss right side of plug collar wall a positive stop is arranged, positive stop also links into an integrated entity with the casting of plug collar wall, when the rolling bearing on socket (2) support of bearing drops in the antiskid groove of plug, then the support of bearing on socket (2) collar wall is keeping off the positive stop of plug outer ring, make plug not continue again to rotate counterclockwise, in order to avoid the rolling bearing on the support of bearing of socket (2) skids off antiskid groove, positive stop on the plug collar wall plays position-limiting action to the rotation of plug, cause the conductive parts in the pinned coupler housing to do closely contact, thereby make contact resistance drop to 0.4 milliohm.Make not easy burn-out of parts such as the interior fusible core of housing, binding post.
Left surface at the boss of plug collar wall has deep-slotted chip breaker, when plug rotates in socket (2), can make the shop bolt that is installed on socket (2) the right circles end face can in the deep-slotted chip breaker of plug collar wall boss, do operation relatively, and be not obstructed, shop bolt is a mark of pinned coupler, the pinned coupler of shop bolt promptly is housed, link with the battery positive voltage on the locomotive under the ore deposit, for the pinned coupler that is unkitted shop bolt, then be connected with battery terminal negative on the locomotive under the ore deposit.
